ABSTRACT:
An integrated device with electrically programmable and erasable memory cells, including one time programmable (OTP) read-only memory cells. A matrix of user memory cells is added at least one row of OTP cells sharing the column selection lines with the other cells. Similarly to the other cells, these have a selection terminal connected to a row selection line. The source terminals of such OTP cells in the row are connected to the device ground through a common selection transistor which is driven from the same row selection line.
